Claims. 1

This invention relates to useful improvements in extension tables.

One of the essential objects of this invention is to provide an extension table which is arranged to be simple in its construction so that it can be manufactured and placed on the market at a minimum of cost, and which at the same time can be conveniently and readily manipulated into and out of its extended position.

Another object of this invention is to provide an extension table wherein the extension leaf can be readily adjusted from one position to another and will be safely held in such position, and wherein such leaf can also be readily withdrawn from the table, for making repairs and the like, without any need of removing screws or bolts and the like.

These and various other objects and advantages are attained with this invention, as will become apparent from the following description, taken in connection with the accompanying drawings wherein the invention is shown in its more desirable form, it being evident that other arrangements and forms of construction may be resorted to in carrying out the objects and purposes of the invention.

In the drawings:

Fig. 1 is a side view illustrating the upper part of an extension table including my invention, and showing one leaf in its extended position and the other leaf retracted.

Fig. 2 is an inverted plan view thereof. taken along line 2--2 of Fig. 1, showing parts in section and parts broken away.

Fig. 3 is a sectional view, taken on line 3-3 of Fig. 2.

Figs. 4 and 5 are partial vertical sectional views showing the extension leaf and its supporting bars in various positions.

Fig. 6 is a sectional view, taken on line 6-6 of Fig. 3.

Fig. '7 is an enlarged fragmentary sectional view, taken on line 'I! of Fig. 3.

8 is a detail view of one form of interen gaging elements provided on the adjoining parts of the table top and the leaf.

Fig. 9 is a sectional view thereof, taken on line 99 of Fig. 8.

Fig. 10 is a detail view of another form of interengaging means; and Fig. 11 is a sectional view thereof, taken on line ll--H of Fig. 10.

Fig, 12 is a detail view of yet another form of such interengaging means; while Fig. 13 is a sectional view thereof, taken on line l3--l3 of Fig.

2 12; and Fig. 14 is a sectional view taken on line l4i4 of Fig. 13.

This invention is illustrated in the drawings in a preferred form of construction, comprising a stationary table part or unit I'5, which includes a frame containing side members or rails IB and end members or rails l1 secured together and mounted on supporting legs l8, and this unit also includes a stationary section or table top l9 which is fixedly mounted on the frame.

A drawer 20 is furnished with this table when desired, and it is preferably supported slidably on guide bars 2| provided on the frame, substantially as indicated in the drawings.

Suitable extension sections or leaves 22 are mounted at the two opposite parts of the table top, either at the two ends or at the two sides of the top, and they are shown herein as positioned at the two opposite ends of this table top I9. A suitable slot for receiving the leaf, in its retracted position under said table top, is therefore herein provided at each end of this table; and this is conveniently and economically accomplished by mounting a strip 23 on each side rail [6, being a trifle thicker than the leaf 22 to provide ample clearance and slidable movement for the leaf, thereby providing a pair of slots 24 between the upper end parts of the side rails and the table top and also a companion slot 24' between the adjoining end rail and said top, for housing the leaf therein.

Each leaf is carried on a pair of bars 25, being secured on the outer parts 26 of said bars, by suitable elements 21. These bars may be constructed of metal or of wood, and are preferably made of tubular metal, thus combining comparative lightness and strength; and each bar is doubly bent to provide a bent intermediate part 28, so arranged that the outer leaf-carrying part 26 of the bar is positioned higher than its inner part 29, but is substantially parallel thereto, as indicated in the drawings. This construction thus provides that all these bars 25 are alike and interchangeable, and no right-hand and lefthand bars are required of different construction, as is usually needed with the known extension tables.

Guideways are provided for each pair of leafcarrying bars 25, and the same include a pair of notche 3| provided in the end rail l1 and also a pair of notches 32 provided in a pair of blocks or saddle members 33 which are secured to the nether side of the table top 19. These guideways are arranged so that the bars are slidably movable in a right-line direction therein and will thus aid in keeping the side of the leaf parallel to the adjoining end of the table top, to bring the extended leaf in correct fitting position with the top.

A stop element 34 is provided at the inner end of each bar 25, adapted to engage the block 33 and normally limit the outward movement of the bar; and this element 34 is adjustably mounted in the bar, so that it can be adjusted to bear under the top #9 and aid in supporting the bar and the leaf in various positions, as indicated in Figs. 3 and 4 of the drawings.

Cooperating interengaging means or elements are provided on the leaf and on the adjoining part of the table top, to retain the extended leaf firmly in position at the correct level with the top; and this means is being provided in either of .several desirable forms, as variously indicated in Figs. 8 to 14 of the drawings.

In Figs. 1 to 9 said interengaging means or ele :ments are shown in the form of a plate or finger 35 which is secured underneath'the leaf 22 and ,has a slotted end pant providing spaced-end portions or tines 36 that engage the shank portion ofa screw 3 between the head 38 of the Screw and the nether face :of the table top i9 from which this screw extends, as best shown in Fig. 9.

.In Figs. 110-and111 such interengaging means or elements are shown in the form of pegs 45 se-- cured to and extending from the leaf 22, adapted to engage in bores 41 provided in-the adjoining .partof the table top Hi.

In .Figs. 12, 13 and lathe interengaging means or elements are shown in the form 'of a latch or tongue 55 which is secured underneath the leaf 22 and projects therefrom toward the table top l9", adapted to engage inla pocket portion 56 of a saddle or strap 5 secured underneath the adjoining partof the table top, as indicated in the drawings.

It should be :noted that with this construction, by using-the top strips .23 on the frame rails and thereby providing \slots :for receiving the'leaves therein, these a side srails and end rails can be economically made of the same stock; and also that hereby the guide notches 3! .in the rails need not be cut .deep .nor weaken the rails. This becomes of considerable importance where theleaf is mounted on .theside of .the top, as customarily the side :rail isalso cut or notched for receiving the slidable drawer, in the known table new on the market; whereas, with my table the guide notches in the top part of the rail are shallow and leave sufficient material .in the rail, between such ,g-uide notches and such a drawer notch in the lower part of the rail, .as to maintain a comparatively strong rail.

It is apparent frornthe above disclosure, as best seen .in Fig.- 4, that the .stop elements 3f normall limit the outward movement of the leaf-carrying bars 25,, by engagin the blocks 33-; and since each of the elements is adjustable in the bar it may furthermore be made to engage underneath the table top IS, .in several positions, as indicated in Figs. .3 and .4, and said elements 34 will then be instrumental. in .holding the extended bars and the leaf in proper position.

.It should be notedthat with this invention the notches 31in the end rail I? and .the notches 32 in the blocks 33. .are arranged so thatby tilting the leaf excessively .upwards asshown .inFig. 5, these elements 34 will clear the blocks with their .notches, and then likewise the railnotches, and thus thepair .of leaf-carrying bars may be readily withdrawn .from the stationary table unit l5, for making repairs and the like, without first removing any screws or bolts or the like as is required with the known extension tables.

t is also apparent that herein the bent intermediate parts 28 of the pair of bars 25 will induce the leaf to be moved upwards automatically as it is being drawn outward, to the position shown in Fig. 4, and will thus assist in placing the leaf in its proper elevated position, to be conveniently pressed against the .table top as shown in Fig. 3. It further appears from Figs. 3 and 4 that when the leaf is in its extended position the inner ends of the bars 25 bear under the saddle blocks '33, and are thus instrumental in holding their outer parts and the leaf in place; and these blocks are also instrumental in limiting the inward movement of the leaf to its retracted posi" tion, as'best shown at the left-hand side of Fig. 2.
